"To one who has faith, no explanation is necessary. To one without faith, no explanation is possible."
--Saint Thomas Aquinas
Since today is the feast day of Saint Thomas Aquinas, a few words of wisdom from him are in order. In school, St Thomas was often teased by his peers, who though him to be dumb--they called him "the dumb ox"--yet ironically he was one of the greatest thinkers ever to live. To return bring the irony full circle, let me note that everybody thought I was a smart person in school, and now I will add my own thoughts, which will be considerably less enlightening than those of St Thomas.
I have said before that faith is like a pair of glasses--it really does alter one's perception of the world. Things which were once muddled can become clear, and things which were lost in the blur become visible. Gaining (or losing) one's faith really does change how one views the world. The change is rarely overnight--it's often gradual--but such things have happened before. Sometimes the change is not so much in what we see, but how we interpret it.
